Claim: US Did Not Seize Its Most Recent Bitcoin Acquisitions, Instead Directly Obtained Them by Guessing the Private Keys

Cobo co-founder Shenyu has claimed that US security forces have accessed the private keys of 120,000 Bitcoins (BTC).

According to Shenyu, this access was made possible not by any “hack” or system breach, but by detecting a randomness error used in generating the private keys.

According to the information shared, the vulnerability affected over 220,000 wallet addresses. The private keys in these wallets were generated by a faulty pseudo-random number generator (PRNG) that operated with a fixed offset and pattern. This made the keys predictable.

According to the findings, all weak wallets within the faulty PRNG range held a total of 136,951 BTC. However, the large withdrawal wave that began after transaction “8b9de493..08f4a4c2” (starting with “95384d1c..8617c9e2”) lasted approximately two hours, and by the time transaction “14bb56a2..07983bcd” reached, the total balance had dropped to 193 BTC. In the following days, this amount decreased to approximately 4 BTC.

Another striking detail about the suspicious transactions is the fact that many transfers used a flat fee of exactly 75,000 satoshis. Experts say this amount is unusual and could offer additional clues about the technical aspects of the incident.
